WhatSyncWhatsApp won't link or got logged out
WhatSync links to WhatsApp as one of your linked devices, the same way WhatsApp Web does. WhatsApp decides whether a link goes through and when a linked device is logged out. Find what your phone or your dashboard says below.
Before you try again
- What should I check first?
- Four things. Your phone is online and WhatsApp opens normally on it. WhatsApp is updated to the latest version. You have fewer than 4 linked devices: in WhatsApp, open Linked devices and log out of one you no longer use. And you link the number of the phone you are holding.
- Which way of linking should I use?
- Either works: the QR code or your phone number with a code. If one fails, try the other from your dashboard. Linking with your phone number is the easier one when you are on your phone and have no second screen to scan from.
Linking with the QR code
- My phone says "Check your connection and try again"
- Your phone read the QR code but WhatsApp did not finish the link. Switch your phone between Wi-Fi and mobile data, update WhatsApp, then try again with the Phone number tab instead of the QR code. If web.whatsapp.com will not link on the same phone either, the problem is between your phone and WhatsApp: wait an hour and try again.
- The QR code expired or will not scan
- A QR code only lasts a short time and refreshes on its own. Keep the page open, click Show QR code again and scan straight away, with your screen brightness up. Or link with your phone number instead.
Linking with your phone number
- WhatsApp says "An error has occurred" when I type the code
- Type the code within 3 minutes of getting it, and check that the number you gave WhatSync is the one on that phone, with its country code. If you asked for several codes in a row, WhatsApp refuses new ones for a while: stop, wait a few hours, then ask for one code and type it straight away. Asking again and again makes the wait longer.
- Where do I type the code?
- WhatsApp sends your phone a notification about linking: tap it and type the code. If no notification comes, open WhatsApp, go to Linked devices, tap Link a device, then Link with phone number instead.
- My code ran out of time
- Each code works for a few minutes. Click Get a new code in your dashboard and type the new one. An older code no longer works once you have a new one.
The passkey step
- My phone says "Couldn't confirm passkey", or WhatSync asks me to confirm it's you
- Some WhatsApp accounts, mostly WhatsApp Business ones, must confirm a new linked device with a passkey. This step needs Chrome, Edge or Brave on a computer, with the free WhatSync extension. Add the extension, go back to your WhatSync dashboard and click Confirm it's you. A tab opens where you confirm with your passkey, on your phone or the computer. Finish before the time shown on the page.
- The passkey step ended before I finished
- WhatsApp only waits a short time. Start linking again from your dashboard, with the extension already added, and confirm as soon as the button appears.
- Can I do the passkey step on my phone or in Safari?
- No. It only works in Chrome, Edge or Brave on a computer. Open whatsync.app there and link the number again.
It worked, then WhatsApp logged it out
- Why was WhatSync logged out?
- WhatsApp logs out a linked device when your phone has not opened WhatsApp for about 14 days, when it is removed under Linked devices on the phone, when you move WhatsApp to a new phone, reinstall it or change your number, or when WhatsApp restricts your account. WhatSync emails you when it happens.
- How do I connect again?
- Open your dashboard and link the same number again, by QR code or phone number. Your plan carries on as it is. You do not pay again or sign up again.
- What happens to my saved messages?
- They stay, and your AI can still search them. New messages are not saved while WhatSync is logged out, so link again soon.
- How do I stop it happening again?
- Open WhatsApp on your phone at least every few days and keep it updated. In Linked devices, WhatSync shows as Google Chrome (WhatSync) or Google Chrome (macOS): do not log out of it when you tidy up your devices.
- WhatsApp restricted my account. Can I still link?
- Not until the restriction ends. WhatsApp shows how long is left in the app. When it is over, link again from your dashboard. WhatsApp restricts numbers it thinks send bulk or unwanted messages. If you do not want anything sent from your number, switch Sending off in Settings.
- My dashboard says "Reconnecting"
- Nothing to do. Short drops fix themselves, usually within a minute. You only need to link again when the dashboard says WhatsApp logged this device out.
Still not linked
- What should I send WhatSync?
- Contact us with the WhatsApp number, whether you used the QR code or your phone number, the exact words your phone showed, and the time you tried. With those four things we can see what WhatsApp answered.
